# Usability Testing & A/B Wireframing for Customer Reviews
Testing how target users interact with review components provides valuable data before writing production code.
---
## 1. Key Usability Metrics to Measure
When running user testing on review card prototypes:
- Time to First Interaction: How quickly users locate review filters or search bars.
- Scannability Index: Whether users notice key summary badges (e.g., Overall Score, Rating Distribution) during 5-second impression tests.
- Scroll Depth: Tracking how far users scroll down feedback feeds on mobile viewports.

## 2. Running A/B Wireframe Tests
Create two visual variants to test engagement:
- Variant A: Compact horizontal card carousel.
- Variant B: Expanded 2-column card grid with histogram summary header.
Evaluate which layout pattern yields higher comprehension and trust ratings in user research panels.
